CONECA (pronounced: CŌ´NECA) is a national numismatic organization devoted to the education of error and variety coin collectors. CONECA focuses on many error and variety specialties, including doubled dies, Repunched mintmarks, multiple errors, clips, double strikes, off-metals and off-centers—just to name a few. In addition to its website, CONECA publishes an educational journal, The Errorscope, which is printed and mailed to members bimonthly. CONECA offers a lending library, examination, listing and attribution services; it holds annual meetings at major conventions (referred to as Errorama) around the country.

CONECA was formed through a merger of CONE and NECA in early 1983. To learn more about the fascinating HISTORY OF THE ERROR HOBBY and THE HISTORY OF CONECA, we encourage you to visit us our main site Here

  • 1989 LIBERTY error?

    I also found this 1989 cent and the word LIBERTY looks strange. I'm not sure if this exists normally in other coins. And the reverse has something going on with Lincoln in the center. Just learning and I don't know the lingo yet. Please review/advise, if any. Thanks!

    Both the obverse and reverse anomalies you mention are the result of bad plating. Those are all gas bubbles with affect the way devices look.

      AKA "Bubbled plating"

        AKA plating blisters

        Contaminants under the copper plating, laid down during the zinc processing, can gas from the heat and pressure from the striking chamber.
